There are both free and fee based DDNS accounts available. The following lists some of the options currently available. If you don’t like any of these, just do a google search for DynDNS providers.<\/p>\n

The instructions for setting up these accounts are typically quick and simple. You pick a domain name, one of your choice, and this name will likely have a suffix appended to it. This part is selected by the provider. This is a very small price to pay for a FREE service. Then this name gets synchronized with your current network IP. That’s it.<\/p>\n
Setting up the router for port forwarding<\/strong><\/h3>\nYou will undoubtedly have more than one device to connect from your local network to the Internet. But there is only one IP assigned to your network. So how can the traffic initiated\u00a0from your DDNS domain name, which resolves to your Internet IP, know which device on your network to deliver the \u00a0message to?<\/p>\n
Simple-Ports…<\/p>\n
Think of the IP for your Internet connection as a post office and the ports as the individual boxes.<\/p>\n
The connection to your device will almost certainly use Transmission Control Protocol (TCP). And TCP identifies the destination by port number. The valid range is 0 to 65535. So for each device on your local network, a port needs to be assigned for delivery of packets from the network.<\/p>\n
The key to making this work is to configure your router to forward packets from the Internet to the intended recipient, that is, the destination port. Hence, the name port forwarding.<\/p>\n
While this is not too difficult to set up, the step-by-step directions for port forwarding are unique for each router. That is simply because router firmwares are all different. The setup\u00a0is typically found in the firewall settings. Here is how to do in with a D-Link DIR-625 router. Just 3 simple steps. 1-2-3… Your router should have similar options for setting up port forwarding:<\/p>\n
Port forwarding\u00a0<\/strong>a D-Link DIR-625<\/strong><\/h3>\n1. First, select the\u00a0ADVANCED menu item from the initial router screen.<\/p>\n

<\/a><\/p>\n <\/p>\n
2.Next, click on the PORT FORWARDING tab.<\/p>\n

<\/a><\/p>\n <\/p>\n
3. Now all you need to do is identify your local network device by IP, assign a port to it, and save your configuration.<\/p>\n

My ISP is AT&T U-verse. Setting up the router they provide for port forwarding was not so obvious, at least at first glance. Since this is such a popular home router, I am also providing port forwarding setup instructions here.<\/p>\n
Port forwarding\u00a0<\/strong>an AT&T\u00a0NGV-589<\/strong><\/h3>\nNow the AT&T router configuration for port forwarding is a bit more tedious. I’ve broken it down into the following 8 steps.<\/p>\n
1. Access your router’s main web portal page and select the Firewall tab.<\/p>\n
![\"AT&T](\"http:\/\/internetofhomethings.com\/homethings\/wp-content\/uploads\/2015\/05\/portforwardatt11.jpg\")

<\/a><\/p>\n3.\u00a0You’ll then be instructed to enter the router access code.<\/p>\n
![\"portforwardatt3\"](\"http:\/\/internetofhomethings.com\/homethings\/wp-content\/uploads\/2015\/05\/portforwardatt3.jpg\")

<\/a><\/p>\n5. Alas, we have now\u00a0arrived at the screen to identify the port! Here, enter a name for your device and the port number(s) you with to assign to your device.
